The latest stars rumored to be in talks to join the panel? The return of previous judge Jennifer Lopez, as well as the addition of rapper will.i.am. However, Will likely won't be able to commit enough time to 'Idol,' according to sources -- which makes sense. He's busy promoting '#willpower' and served as a judge on the U.K. edition of 'The Voice,' which could present a conflict of interest.

What's more, sources say no one from 'Idol' has approached Lambert just yet, despite the 'Trespassing' singer being pretty enthusiastic about the chance to hop on over to the judges' table. Someone call him!
